television (3DTV), an interactive free viewpoint selection application has
received more attention so far. This paper presents a novel method that
synthesizes a free-viewpoint based on multiple textures and depth maps in
multi-view camera configuration. This method solves the cracks and holes
problem due to sampling rate by performing an inverse warping to retrieve
texture images. This step allows a simple and accurate re-sampling of synthetic
pixels. To enforce the
spatial consistency of color and remove the pixels wrapped incorrectly because
of inaccuracy depth maps, we propose some processing steps. The warped depth
and warped texture images are used to classify pixels as stable, unstable and
disoccluded pixels. The
stable pixels are used to create an initial new view by weighted interpolation.
To refine the new view, Graph cuts are used to select the best candidates for each unstable pixel. Finally, the
remaining disoccluded regions are filled by our inpainting method based on
depth information and texture neighboring pixel values. Our experiment on
several multi-view data sets is encouraging in both subjective and objective
results. Furthermore, our proposal can flexibly use more than two views in
multi-view system to create a new view with higher quality.
